Abstract

This work presents a new methodology based on three well-known qualitative techniques (Focus Group, Nominal Group Technique and Delphi method), with a view to harmonising their potentialities and reducing their limitations, through application in real contexts with experts who are professionals in their respective activities.The main contribution of this methodology is its joint consideration of the needs of the investigators and also of experts who act in professional contexts, in order to improve the effectiveness of preceding techniques in achieving the scientific and social objectives of the study.We have tested this methodological approach in three real cases, with experts holding different responsibilities in different companies and public organisations, and the results secured are highly satisfactory, due to both the quantity and quality of the proposals obtained, and the satisfaction exhibited by the experts taking part, with regard to the research methodology. ?? 2011 Elsevier Inc.
